吐哈鲁克沁稠油油田玉北区块是2014年重点开发区块,井型以大斜度定向井为主。针对玉北区块具有封固段长、大斜度和完井钻井液影响胶结质量的难点,为实现有效封隔储层,提升固井质量,本文简要阐述了一套新的速凝水泥浆体系及高效顶替配套固井工艺。该工艺经过现场应用,取得了良好效果,此工艺也为解决玉北区块固井难题探索出了一条有效的技术途径。
The Tuyukuru Qinsuya Oilfield The YuBei block is a key development block in 2014 and the well type is mainly a high-gradient directional well. In view of the difficulty of sealing section length, large slope and completion drilling fluid affecting the cementation quality of YuBei block, in order to effectively pack the reservoir and improve the cementing quality, a set of new quick setting cement System and efficient replacement cementing process. The process has been applied on site and achieved good results. This process also explored an effective technical approach to solve the well cementing problems in the Yubei block.
